Seismic Reflection Method. 6

Seismic reflection is the method which always gives the most detailed information. Other methods cannot be compared to it. The seismic section below corresponds to the line marked with arrows on the isochrone map beneath it. This section crosses three faulted anticlines and two salt domes. The interpreter has been able to pick a number of horizons, one of which is mapped in ISOCHRONES and shown below. With knowledge of the velocities, which may be obtained from the same recordings, it is possible to derive and ISOBATH MAP from the ISOCHRONE MAP. A combined seismic interpretation diagram showing a seismic reflection profile above and a time-structure contour map below. The upper section displays subsurface seismic reflections along an approximately 80-kilometre line using two-way travel time. The lower section shows contoured structural features derived from the seismic data, including labelled anticlinal structures and salt intrusions. Arrows indicate the position of the seismic line on the map. The diagram illustrates the relationship between seismic profiles and mapped geological structures. https://www.w3.org/1999/xlink" xlink:href=" https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003761020/e10523ab-dbe3-4c4f-8f3e-863ae3683950/content/pg382_1.tif "/>
